To all (whom it may concern:

Be 1t known that I, FREDERICK WILLIAM VOGT, residing at Philadelphia, inthe county counteracting swinging movements of railway cars of the typeand construction illustrated and described in the issue of the Eugineer,London, of October. 24th, 1902, which by gravity are held in anoperative position suspended from a structure, and in such connection itrelates more particularly to mechanism connected with the car, which bydeveloping and bringing forces similar .to those developed in agyroscope into action, resists and thus counteracts the swingingmovements of the suspended car, which are caused by'wind'pressure orhigh speed of travel. I

The nature and scope of my invention will be more fully understood fromthe following description taken in connection with the accompanyingdrawing,-illustrating partly in elevation and partly in section aportion of a supporting structure, a car suspended therefrom, and themechanism, forming the sub-.

ject matter of the present application, connected with the car.

Referring to the drawings, 1 represents the car to the roof 2 of whichis suitably secured a bracket 3, supporting a tractionwheel 4, and acasing 7 inclosing a motor, not shown, for driving the wheel by means ofa gear-whee] 13. The wheel 4 engages a rail 5 carried by a structure 6,which forms the support from which the car 1, by means of the bracket 3,is suspended. Preferably on the roof 2 of the car 1 are arrangedbrackets 8, supporting a shaft 9, to which are secured disks oriiy-wheels 10, a gear-wheel l1 and a brake-disk 12. The gear-wheel 11meshes with a gear-wheel 15 (.f an electric motor 14, likewise placed onthe roof 2 of the car, which motor by means of its gear-wheel 15 and thegear-wheel 11, sets the shaft 9 and the disks 10 mounted thereon inrapid rotation, in a direction similar to that in which .thetraction-wheel 4 is rotated. 'As long as the car 1,

by force of gravity, is held in a vertical position, the forces whichhave been developed by the rapid rotation of the shaft 9 and disks thecar is moved out'of its normal vertical position and is inclined as wellas the shaft 9, these forces are brought into action and oppose in awell known manner such movements of the shaft 9. Thus the shaft 9 willcounteract, by the intervention of the brackets 8, the swinging movementof the car 1, and will thus aid the force of gravity to move the carback to its normal vertical position, and to maintain the same therein.

In order to stop the action of the forces developed by the rotation ofthe shaft 9 and disks 10, a brake-band 16 engagin the brakedisk 12 andwhen tightened 't ereon, by

means not shown, will prevent the further rotation of the shaft-9 anddisk 10, and will the action of centrifugal force, in taking curves inthe rail 5, on the supporting structure 6.

Having thus described the nature and ob ject of my invention, what Iclaim as new and desire to secure by Letters Patent is 1. In a device ofthe character described, a structure, a car suspended from saidstructure and held in a normal operative position by gravity, a shafthaving disks, and means for rotating said shaft and disks, said shaftand disks when rotated adapted to resist swinging movements of said car.

'2. In a device of the character described, a structure, a car suspendedfrom said struc-' ture and held in a normal operative position bygravity, a shaft, means for connecting said shaft with said car, disksmounted on said shaft, means for rotating said shaft and disks, saidshaft and disks when rotated adapted to counteract swinging movements ofsaid car.

In a device of the character described, a stru(- tu1'e,.a rail carriedby said structure, a car having a traction-wheel traveling on said rail,said wheel adapted to hold said car suspended from said rail and permitof holding of thc car by gravity in a vertical operative positionthereon, a. shaft having disks, means for rotating said shaft and disks,and said shaft and disks when rotated adapted to resist swingingmovements of dd car.

4. In a device of the charac'tcrdescribcd, a structure, a rail carriedby said structure, a wheel traveling on said rail, a car, means forconnecting said wheel with said car, said wheel in conjunction with saidmeans adapted to hold said car suspended from said rail, a shaft carriedby said car and held by the same in a position at right angle to saidwheel, disks mounted on said shaft, and means for rotating said shaftand disks, said shaft and disks when rotated adapted to assist force ofgravity to return said car to a vertical position when removedtherefrom.

5. In a device of the character described, a structure, a rail carriedby said structure, a wheel traveling on said rail, a car having; a roof,means for connecting said wheel with said car, said wheel in conjunctionwith said means and said roof adapted to hold said car suspended fromsaid rail, brackets carried by said roof, a shaft carried bysaidbrackets and held by the same in a positionat right angle to saidwheel, disks carried by said shaft, means for rotating said shaft and bythe same said disks, .said shaft and disks when rotated adapted toassist the force of gravity to return said car to a vertical posi-.,tion when removed therefrom.

6. In a'device of the character described, a structure, a rail carriedby said structure, a wheel traveling on said rail, a car, means forconnecting said wheel with said car, said wheel in coinunctioii withsaid means adaptrail and adapted to hold said car suspended therefrom,brackets carried by 'said car, a

shaft carried by said brackets and held by l the same in a positionsubstantially at right angle to said wheel, disks and agear-wheelmounted on said'shaft, means meshing with said gear-wheel adapted whenactuated to rotate said shaft and by the same said disks,

said shaft and disks when rotated adapted to aid the force of gravityinreturning the car to a normal operative position when removed therefrom,and means carried by said shaft adapted to arrest the rotary movementthereof.

8. in a device of the character described, a structure, a rail carriedby said structure, a car having a tractionewheel traveling on said rail,said wheel adapted to hold said car in asuspended position from saidrail, brackets carried by said car, a shaft carried'by said brackets andheld by the same in a position substantially at right angle to saidtractionwheel, disks,a gear-wheel and a brake-disk mounted on saidshaft, a motor carried by said. car having a gear-wheel meshing with thegear-wheel of said shaft and adapted by the intervention of thegear-wheels to set said shaft and disks in rapid rotation, said shaftand disks when rotated adapted to aid the/force of gravity in returningthe car to a normalv operative vertical position when removed therefrom,aiid means engaging the brake-disk of said shaft. 1 In witness'whereof,I have hereunto se my signature in the presence of two subscribingwitnesses.
